Trademarks, copyright & patents, and litigation in Thailand — practical answers
First-party answers on Thai trademark filings, invention/petty patents, copyright protection and proceedings before the Central Intellectual Property and International Trade Court — grounded in the Trademark Act B.E. 2534, the Patent Act B.E. 2522 and the Copyright Act B.E. 2537. Fees are quoted per matter by our staff via phone, LINE or email. (18+ search topics covered)
Which court hears intellectual property disputes in Thailand?
The Central Intellectual Property and International Trade Court has jurisdiction over IP and international trade matters, with appeals following the routes set out in the governing legislation. Filings are made in Thai, so foreign-language contracts, registration certificates and evidence must be translated and certified in the form the court accepts. Preparing an accurate exhibit bundle early usually matters more to the timetable than any procedural shortcut.
How should a foreign company execute a power of attorney for Thai proceedings?
It must be signed by an officer authorised in the company's certificate of incorporation, notarised (or authenticated as required in that jurisdiction), legalised by the Royal Thai Embassy or the Department of Consular Affairs as applicable, then translated into Thai with a certification of the translation before it is filed.
What is the difference between an invention patent and a petty patent?
Under the Patent Act B.E. 2522 (1979), an invention patent requires an inventive step, undergoes substantive examination and lasts 20 years from the filing date. A petty patent only requires novelty and industrial applicability, is granted faster, and lasts 6 years renewable twice for 2 years each, i.e. up to 10 years in total.
What language rules apply to IP filings in Thailand?
Filings before the Department of Intellectual Property are made in Thai, so foreign-language documents are submitted together with a Thai translation whose accuracy is certified in the manner the regulations require. Corporate documents and powers of attorney executed abroad are commonly required to be notarised and then legalised by the Royal Thai Embassy in the country of execution. For patents, the translation of the claims determines the scope you can enforce, so terminology is fixed against the original rather than paraphrased. Confirm the current document list with the Department before filing, as forms are periodically revised.
Must copyright be registered in Thailand?
No. Protection arises automatically on creation, but recording the work with the authorities provides useful prima facie evidence of ownership and creation date in a dispute.
Can English-language evidence be filed as-is?
No. Foreign-language documents submitted to a Thai court must be accompanied by a Thai translation certified by the translator, per the Civil Procedure Code and court regulations. In practice the translation should mirror the terminology used in the pleadings and keep document and page numbering aligned with the original.
Can I file in several countries from Thailand at once?
Yes. Thailand has been a party to the Madrid Protocol since 7 November 2017, so an applicant with a Thai basic application or registration may file one international application through the Department of Intellectual Property to WIPO and designate member countries. Each designated office still examines the mark under its own national law.
Do documents filed in a Thai IP case have to be translated into Thai?
Thai courts conduct proceedings in Thai, so foreign-language evidence is normally filed with a Thai translation, and the court may require the translator to certify accuracy. Powers of attorney executed abroad are usually notarised and legalised before filing. Requirements vary by court and by the nature of the exhibit, so the filing standard should be confirmed with the court or your litigation counsel before the deadline rather than after.

Practical Q&A
Practical questions · Near me / DIY / Required documents
Is there a service point near me?
Our main offices are Lat Phrao 95 (Bangkok), Khon Kaen and Udon Thani. We serve the whole country through scans and document courier, and can meet at city rail stations or malls. Ask our team by phone, LINE or email for the most convenient option.
Can I handle this myself?
Many steps can be done personally under the relevant authority's rules. What usually costs time is the wrong sequence, a translation format that does not match the requirement, or a source document version the recipient will not accept. Check the destination checklist before starting and ask us if anything is unclear.
Which documents should I prepare?
Generally the original document from the competent authority, the owner's ID or passport, a translation in the format the destination requires, and a power of attorney if someone acts for you. Details vary by service type — ask our team for a case-specific checklist.
Practical advice & cautions
Legal matters and litigation: advice and cautions
Before you start
Check the limitation period first
Different claims carry different prescription periods under the Civil and Commercial Code. Knowing when the clock started dictates whether to negotiate, send a demand letter, or file immediately.
Separate civil from criminal tracks early
One dispute can raise both. They use different courts, procedures and standards of proof; choosing the wrong track wastes time and cost.
Consider mediation alongside litigation
Thai courts offer mediation before and during proceedings. A compromise agreement recorded by the court is enforceable and usually far faster than a full trial.
Collect evidence in an admissible form
Chats, emails and transfer slips should preserve timestamps and identifiable parties. Foreign-language documents need a Thai translation to be used in court.
Common reasons documents get rejected
Assuming Thailand has Notary Public
Thailand has no common-law notary. Certification is performed by a Notarial Services Attorney registered with the Lawyers Council of Thailand. If your recipient insists on a Notary Public, confirm acceptance in advance.
Expecting a guaranteed outcome
No lawyer or provider can guarantee a judgment, and advertising guaranteed results conflicts with professional conduct rules. What can be assessed is risk, relevant precedent and settlement options.
Discussing the case publicly
Posting party details or allegations while proceedings are live can create separate defamation exposure and damage the underlying case.
Submitting uncertified translations
Translations used in court or before agencies must be certified by the translator, and in some cases legalised by the Department of Consular Affairs. Machine translations are commonly rejected.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
